BRASS REVERSIBLE lJ LATCH Appncaun flied April 22,

The main object of this invention is to provide a reversible latchhaving few parts, these parts being simple and economical to produce andeasily assembled.

A further object is to provide a reversible latch well adapted for useon heavy doors.

Objects pertaining to details and economies of my invention will`denitely appear from the description to follow. The invention isdeiined in the claims.

A structure which embodies the features of my invention is clearlyillustrated in the accompanying drawing, in which:

Fig. 1 is an inverted view of my improved latch with the base plateomitted.

Fig. 2 is a detail view mainly in longitudinal section on line 2 2 ofFigs. 1 and 3.

Fig. 3 is a fragmentary view on a line corresponding to line 3 3 of Fig.2.

Referring to the drawing, the housing 1 of the embodiment illustrated isa stamping having an opening 2 in its rear wall and an opening 3 in itsfront wall through which the bolt 4 projects and is adapted to swing.The base plate 5 is housed within or covered by this housing.

Thepivot 6 is supported at its upper end by the inturned arm 7 formed bystrikingin a portion of the rear wall to form the opening 2. The bolt 4:is mounted on this pivot with its front end projecting through theopening 3. The frontend is provided with a strike or keeper engagingroller 8.

The bolt is longitudinally slotted or recessed at 9 to receive thespring 10 and the inwardly projecting arm 11 of the reciprocating togglemember 12. This toggle member has a longitudinal slot 13 engaging thepivot. The spring is disposed between the pivot and the arm 11 undercompression.

The rocking or pivoted toggle member 14 is pivoted at 15 on thereciprocating toggle member 12 and has spaced fulcrum points 16rockingly engaging the front wall of the housing above the opening 3therein, the front wall of the housing constituting asupporting abutmentfor the'toggle. f 'Y The side walls 17 of the housing limit the lateralmovement yof the pivoted toggle member so that when the bolt is swung onits piv# i929. serial 110.357,07.

ot, the pivot`15 of the pivoted toggle member swings with the bolt,thereby rocking the pivf oted toggle member on one of itslfulcrum pointsand subjecting the spring l0 to still furtherlcompression, so that whenthe bolt is released itis again returned to its central position withboth fulcrum points of the toggle member bearing against thefront wallof the housing. j y t The structure is very simple and economical in itsparts, they partsfare strong and durablel and easily'assembled.

`r Having thus described my invention whaty I lclaim as new and ydeslreto secure by Letters Patent is: Y v

1; In a reversible latch, the combination with a housing, a pivotwithin'said housing, a longitudinally slotted bolt'mounted on said ipivot, a reciprocating toggle member slotted to embrace said pivot andprovided with an.

arm projecting rinto said slotin said bolt` a toggle Ymember pivotallymounted on saidreciprocating toggle member and provided with a pair rofspaced fulcrum points rockingly engaging the front wall of the housing,

the side walls of the housing constituting supports'for the end of saidpivoted toggle member, and a spring disposed rinsaidfslot in said boltbetween said yreciprocating toggle member and said pivot.

2. In aV reversible latch, the combination withk a housing, a pivotwithin said housing,V

a longitudinally slotted bolt mounted on said pivot, a reciprocatingtoggle member slotted to embrace said pivot and provided with an armprojecting into said slot in said bolt, a toggle member pivotallymounted on said reciprocating toggle member and provided with a pair ofspaced fulcrum points, and a spring disposed in said slot in said boltbetween saidreciprocating toggle member and said pivot.

3. In a reversible latch, the combination with a housing, a boltpivotally mounted within said housing for swingingmovement, areciprocating toggle member engaged with said bolt to swing therewith, asecond toggle member pivotally mounted on said reciprocating togglemember and provided with spaced fulcrum points rockingly engaging thefront wall of said housing,the side walk of the housing constitutingsupports limiting the lateral movement of said pivoted toggle member,and a spring acting on said reciprocating toggle member to yieldinglyhold both fulcrum points of the pivoted toggle member in engagement withtheir supporting abutments.

4. In a reversible latch, the combination with a housing, a boltpivotally mounted within said housing for swinging movement, areciprocating toggle member engaged with said bolt to swing therewith, asecond toggle member pivotally mounted on said reciprocating togglemember and provided with spaced fulcrum points, and a spring acting onsaid reciprocating toggle member to yield* ingly hold both fulcrumpoints of the pivoted toggle member in engagement With their supportingabutments.

5. In a reversible latch, the combination of a support provided with apivot, a bolt mounted on said pivot, a reciprocating toggle memberslotted to engage said pivot and having slidinr engagement with saidbolt, a. second toggle member pivotally mounted on said reciprocatingtoggle member and provided with a air of spaced fulcrum points, saidsupport eing provided with coacting supporting abutments, and a springacting on said reciprocating toggle member to urge said pivoted togglemember against its supporting abutments.

6. In a reversible latch, the combination of a support, a bolt mountedon said suport for swinging movement, a reciprocatmg toggle memberhaving sliding engagement with said bolt, a second toggle memberpivotally mounted on said reciprocating toggle member and provided witha pair of spaced fulcrum points, said support being provided withcoacting supporting abutments, and a sprino' actingv on saidreciprocating toggle mem r to urge said pivoted toggle member againstits supporting abutments.

In witness whereof I have hereunto set my hand.

ANDREW EKMAN.
